摘要：

The mass spectra of different steroidal compounds having a lactone-side chain were recorded. The fragmentation pattern of the tetracyclic steroid system is not modified by the structure of the lactone ring. Except for parent ion value and the losses of the substituents at C-3 and C-20, the method is apparently not useful for characterization of the lactone ring itself. The attachment position of the steroid nucleus to the lactone ring can be differentiated by the relative intensity of the peak at m/e 85. © 1979.
